|discussion=<p><i>Erythranthe arvensis</i> usually is easily recognized, characterized by its annual duration (but commonly rooting at proximal cauline nodes, suggestive of a rhizomatous habit), glabrous stems with nodes relatively few and remotely spaced, depressed-ovate leaves with margins often sublyrate (lacerate-lobed to subpinnatifid) at the base, distal leaves and bracts densely villous with vitreous eglandular hairs, other leaves glabrous, and corollas varying in size from relatively small but perhaps chasmogamous (the type of <i>Mimulus</i> arvensis) to even smaller (cleistogamous; the type of M. micranthus). The breeding system is consistently autogamous. The relatively short and even-sized calyx lobes that do not turn upward to close the orifice have been considered diagnostic of <i>E. arvensis</i>. This feature is evident in some plants, but others (perhaps reflecting gene flow from other species) have a longer adaxial calyx lobe and abaxial lobes that turn upward variably.</p>
